Icelandic volcano previously dormant for 800 years erupting again

(NEW YORK) — A once long-dormant volcano in Iceland is erupting again and impacting activity in a populated region nearby.
The volcano, on the Reykjanes peninsula in southwestern Iceland, began erupting at Sundhnukar on Wednesday night and peaked at about 2 a.m. local time Thursday, according to the Icelandic Meteorological Office. It has prompted evacuations at the Blue Lagoon, an iconic tourist destination, and the nearby town of Grindavik.
West Iceland’s volcano is a rift activity volcano, which involves the earth being pulled apart in two different directions through the Mid-Atlantic Ridge, rather than a cone erupting magma through a central pipe, Thomas Algeo, a professor of earth sciences at the University of Cincinnati, told ABC News. The style of eruption is “much less dangerous, because most of the activity involves slow moving basaltic lava flows,” he added.
“It’s a style of volcanic activity that is effusive, slow flowing, not violently eruptive, like would be the case with a subduction zone volcanic system” Algeo said.
The fissure that was created on Wednesday night stretched about 1.8 miles long, according to the country’s meteorological office. This is the volcano’s seventh eruption this year, according to Iceland’s Department of Civil Protection and Emergency Management.
These types of eruptions are “spectacular” sights, because once a fissure opens up, a large supply of magma oozes out, Tobias Fischer, director of the Volatiles Laboratory at the University of New Mexico, told ABC News.
The eruption activity is “typical” for these types of systems, said Shawn Willsey, a geology professor College of Southern Idaho who has been conducting livestream tours using drones above the lava flows on YouTube. Once the lava erupts, the pressure is relieved and magma starts to fill into the shallow storage zone below — repressurizing the system and setting the stage for the next eruption, Willsey said.
“It’s known that this region goes through these episodes where there are a lot of these eruptions,” said Fischer, who has flown drones into eruption gas clouds to collect samples and analyze the composition of the carbon for his research.
By Thursday afternoon, the lava had reached the parking lot of the Blue Lagoon and consumed a service building, The Associated Press reported. There is no danger to the area, and the flights out of the Keflavik International Airport have not been affected, according to the civil protection agency.
Gas emitted from the eruption is expected to move south and out to sea, according to emergency officials.
Video taken from Grindavik show rivers of fast-moving lava flowing from the rift zones, where the lava can be seen spewing from the ground.
The ongoing eruption is “significantly smaller” than the eruption that took place in August, according to the meteorological agency.
Iceland is known as a “hot spot” for volcanic activity, Algeo said.
There are 32 active volcano systems in the region spread across three rift zones spread to the north, south and west — all part of the Mid-Atlantic Ridge, a mountain range that mostly runs down the middle of the Atlantic Ocean.
But in Iceland, the mountain range comes above the ocean certain due to “an excessively high production of magma in that area,” Algeo said.
Iceland’s western rift zone, also known as the Reykjanes-Langjökull rift zone, was active prior to the 13th century. These types of eruptions tend to have every 1,000 or so years, Fischer said,
“The big question is, is this going to continue on for centuries?” Willsey said.
In 2021, the volcano in western Iceland became active again. There have been 10 eruptions since there, seven of which have occurred in 2024, according to Icelandic officials said.
During the last 800 years, the majority of volcanic activity were in the north and east volcanic zones — both lightly populated regions, Algeo said. But western Iceland, which includes the capital of Reykjavik, is highly populated.
“They were in a nice little valley up in the mountains, and so that lava was pretty well contained,” Willsey said, adding that lava in those regions are “tourist-friendly” eruptions that can be enjoyed with little threat.
The recent eruptions in western Iceland have damaged infrastructure and property and forced residents to relocate, according to AP.
Previous eruptions throughout history have caused destruction in Iceland, Algeo said.
A large eruption that took place in 1783, known as the Laki eruption, is one of the worst in recorded history. It spewed so much toxic volcanic gasses across the landscape that it killed off most of the local farm animals and reduced the harvest, leading to starvation for about 25% of the population, Algeo said.
Eruptions on the Reykjanes peninsula in December 2023 triggered toxic gas warnings, causing emergency managers to fear that the pollution would spread to the capital.
A disruptive eruption at the Eyjafjallajokull volcano in 2010 disrupted trans-Atlantic air travel for months due to ash being spewed into the air.
(NEW YORK) — The climate crisis is not a distant threat; it’s happening right now and affecting what matters most to us.

Dangerous hurricanes are being made even worse because of climate change, study finds
Hurricanes are getting stronger, and humans are primarily to blame. A new study from Climate Central adds to a growing body of evidence that human-amplified climate change is indeed leading to more intense storms.
The study, published in the journal Environmental Research: Climate, found that 84% of Atlantic hurricanes between 2019 and 2023 were, on average, 18 mph stronger because of climate change. That additional wind speed resulted in 30 hurricanes reaching an entire category higher in strength (Category 3 to Category 4 or Category 4 to Category 5, for example) compared to a world without human-amplified climate change.
The researchers say sea surface temperatures are being made hotter by global warming, fueling these rapidly intensifying cyclones. The authors cite Hurricane Milton as an example. They found that Milton intensified by 120 mph in under 36 hours. At the time, ocean temperatures were at record levels or near record levels, which Climate Central’s Climate Shift Index: Ocean determined were made 400 to 800 times more likely by climate change.
Over the past half-century, the ocean has stored more than 90% of the excess energy trapped in Earth’s system by greenhouse gases and other factors, according to the National Oceanic and Atmospheric Administration.
“Every hurricane in 2024 was stronger than it would have been 100 years ago,” Dr. Daniel Gilford, climate scientist at Climate Central and lead author of the study and report, said in a statement. “Through record-breaking ocean warming, human carbon pollution is worsening hurricane catastrophes in our communities.”
The researchers identified three storms between 2019 and 2023 that became Category 5 hurricanes, the highest level on the scale, because of our changing climate.
When the scientists applied the same study methodology to storms in 2024, they determined it was unlikely Beryl and Milton would have reached Category 5 status without the impact of climate change. And they found that every Atlantic hurricane in 2024 saw an increased maximum wind speed, ranging from 9 to 28 mph, because human-amplified climate change resulted in elevated ocean temperatures.
Since 1980, tropical cyclones, a generic term for hurricanes and tropical storms, have cost communities $1.4 trillion in damages and claimed more than 7,200 lives, according to The National Center for Environmental Information.

Biden pledges $325 million in clean tech funding for developing nations
On Tuesday, the Biden administration announced $325 million in funding to the Clean Technology Fund (CTF) for global clean energy projects. The funding comes as climate leadership conferences continue worldwide, with COP29 underway in Azerbaijan and the G20 summit in Brazil.
Projects range from implementing renewable energy sources, like solar and wind, to more efficient energy use in transportation.
The Clean Technology Fund provides money for permanent climate projects for middle-income and developing countries, allowing them to jump the financial hurdle and implement much-needed new green tech and energy.
Nine countries currently give money to the Fund through grants and loans. Operated by the World Bank, the program distributes money to eligible countries through global development banks.
This financial commitment is another example of the Biden administration trying to lock in climate funding and programs before President-elect Donald Trump takes office.
Since 2022, the U.S. has contributed $1.56 billion in concessional loans to the fund, and in October of this year, they contributed another $20 million in grants. Since it was established in 2008, the Fund has contributed $7.28 billion in loans and grants globally.
A report released last week highlighted that advancing climate progress in middle-income countries is crucial for setting the world on a path to achieving carbon neutrality by 2050. These countries are not only the most vulnerable to the impacts of climate change, but they also host the majority of the world’s nature and biodiversity.

Countries pledge to reduce potent greenhouse gas that comes from food waste at COP29
As the world’s nations try to decide on a plan of action for limiting the impacts of climate change, the head of the United Nations Environment Programme says reducing methane emissions could be the “emergency brake” the world needs.
Methane is a potent greenhouse gas responsible for about 30% of the rise in global temperatures since industrialization, according to the International Energy Agency.
“Reducing methane emissions this decade is our emergency brake in the climate remit,” Martina Otto, head of the Secretariat, Climate and Clean Air Coalition at the UNEP, said at a press conference with the COP29 presidency.
“To cut the emergency we need to harness the fact that methane has a much higher global warming potential and is shorter lived in the atmosphere, which means we can curb near-term warming.”
Tuesday is food, water and agriculture day at COP29 – an occasion marked this year by a new agreement to cut methane emissions from food waste.
Over 30 countries have already committed to the Declaration on Reducing Methane from Organic Waste, which targets methane emissions from organic waste like food. The move complements additional global efforts to tackle methane emissions, including the Global Methane Pledge, which aims to reduce methane emissions by 30% by 2030.
“Urgent work is needed to help the agricultural sectors adapt to a warming planet,” COP29 lead negotiator Yalchin Rafiyev said.
Rafiyev explained that the Baku Harmoniya Climate Initiative for Farmers — an effort launched by the UN Food and Agriculture Organization (FAO) and the COP29 presidency — will give farmers tools for building climate resilience and secure funding.
“We are also committed to taking every opportunity for mitigation, particularly on methane,” Rafiyev said, noting previous COP’s progress on methane emissions. “We must address all the major sources of methane emissions, including fossil fuels, agriculture and organic waste.”
“Transforming agriculture and food systems is going to be critical if we are to achieve the Paris Agreement, whether it’s on the side of adaptation and building resilience, or indeed on the side of mitigation,” Kaveh Zahedi, director of the Office of Climate Change, Biodiversity and Environment at the FAO, said. “And on this food, agriculture and water day, we’re so delighted that the cop 29 presidency has been shining a light on this.”

UN climate lead says millions of lives are at stake and delegates should ‘cut the theatrics’
As COP29, the annual U.N. global climate conference, heads into its second and final week, the United Nations’ top climate representative is reminding delegates of what’s at stake if they fail to act now.
During his opening remarks on Monday, Simon Stiell, the U.N. climate change executive secretary, chastised the delegates, warning them that they are losing sight of the forest because they are “tussling over individual trees” and that “bluffing, brinksmanship and pre-mediated playbooks burn up precious time.”
“So let’s cut the theatrics and get down to real business,” he said.
Later in the day, Stiell urged climate leaders and public officials to unite on adaptation policy and finance.
“This year, we saw how every bit of preparation – every policy, every plan – is the difference between life and death for millions of people around the world,” Stiell said.
Stiell emphasized that we know how to adapt to our changing climate technologically but need the will to act.
“We have the tools, the science, the ability to achieve these outcomes,” he said.
The biggest roadblock, he said, is ensuring countries have enough money to do the work.
“Of course, we cannot ignore the adaptation elephant in the room: there is a stark financial gap we must bridge,” Stiell said.
According to Stiell, the expenses associated with adaptation are rapidly increasing, especially for developing nations. By 2030, these expenses could amount to $340 billion annually and soar to $565 billion annually by 2050. Without proper funding, he said billions of lives are on the line.
“The IPCC’s Working Group II report told us that almost half the human population live in climate vulnerable hotspots, where people are 15 times more likely to die from climate impacts,” Stiell said.
Stiell encouraged public and private sector funders to rise to the occasion and meet global needs in new ways.
“Think beyond traditional grants and loans,” Stiell said. “Philanthropies, the private sector, and bilateral donors must step up with the urgency that this crisis demands.”
He added, “The funding exists. We need to unlock and unblock it.”

Hundreds of US counties lack sufficient air quality monitoring
Cities, counties and government agencies use air quality monitors to measure the pollutants and particulates that can cause significant health problems. However, according to a new report, hundreds of counties across the United States lack these essential measurement tools.
According to the American Lung Association’s 2024 State of the Air report, more than two-thirds of U.S. counties do not have official ground-based air quality monitoring stations. As a result, dangerous levels of pollution are going undetected and unaddressed.
The association used satellite data to estimate that 300 of the 2,700 U.S. counties with incomplete or no air monitoring data had potentially failing grade levels of fine particulate matter between 2020 and 2022.
Lexi Popovici, lead report author and a senior manager of the American Lung Association, said satellite data could help fill the data gap left by the missing air monitors and help people and officials, particularly in rural areas, take protective measures. She said the technology could also supplement existing ground monitors and ultimately create a more comprehensive air quality monitoring system.
“Using satellite data actually helps fill in those gaps to identify pollution in places that might otherwise go undetected, and this can help millions of Americans understand what air quality they are breathing,” Popovici said.
Fine particulate pollution is a mix of solid or liquid particles suspended in the air – smaller than a strand of human hair – that can be present even in air that looks clean, according to the EPA. These pollutants are considered the most dangerous forms of air pollution and are linked to asthma, lung and heart disease, and other respiratory health issues.
Popovici said subsequent reports will focus more on the potential of community air quality resources and ways to mitigate environmental injustices.
A forensics doctor described seeing expressions of fear on the faces of many of the recovered political prisoners, but most of the bodies are decomposed; ABC News
(DAMASCUS, Syria) — Family members and friends of thousands of missing Syrians are continuing their search for those disappeared by former President Bashar Assad’s regime across 14 years of civil war, as victorious rebel forces begin building a transitional government.
Crowds gathered outside a hospital in the capital of Damascus to pore over images of mutilated bodies recovered from the infamous Saydnaya prison — once described by Amnesty International as a “human slaughterhouse.”
Among them was Abdullah, who was told that his brother was arrested in 2013 and died in 2016. Abdullah told ABC News he had been given no other information then or since and that he came to the hospital in the hope of identifying his brother among the dead.
Abdullah did not find his brother’s body. He told ABC News he would continue his search at another hospital where released prisoners were being treated.
In a morgue inside the hospital, one man found his son among the bodies. Mohammad, 20, was a political prisoner taken into custody in October, his father said. Security Forces also took the father into custody and held him for 60 days, before releasing him.
Mohammad was killed just two months before the spectacular collapse of Assad’s regime, the man said. Holding his 15-year-old younger son close, the bereaved father told ABC News he feels there are brighter days ahead despite his loss.
Some 157,000 people disappeared into regime prisons and other facilities between 2011 and 2024, per an estimate by the Syrian Network for Human Rights.
A forensics doctor in the hospital morgue told ABC News he identified the bodies of about 37 people, most of whom were being held in the Saydnaya prison.
Many of the bodies had signs of torture and many of them suffered malnutrition; some of the bodies have almost no muscle tissue between the ribs due to extreme malnutrition, Dr. Sarah Melhem, a forensics doctor at the hospital, told ABC News. Many have signs of being shot, including entry and exit wounds, while others have signs of torture, including bruises, wounds and scars.
Some of the recovered bodies have expressions of fear on the faces while others are decomposed, Melhem said.
“These are political prisoners, so these prisoners have maybe spent a long time in the prisons so the torture signs [have] dissolved,” Melhem said.
Many of the bodies showed signs of being shot, bearing entry and exit wounds. Others had signs of torture including bruises, wounds and scars. Some of the recovered bodies have expressions of fear frozen on their faces, while others are decomposed, Melhem said.
“I have a cousin who was a political prisoner, but we don’t know anything about him,” Melhem said. “We don’t see him. He was arrested from about 2013 and we don’t know anything about him,” Melhem said.
Under Assad, people were taken into custody for things as simple as a Facebook post, Melhem said.
“I believe that this is a criminal system and all of the Syrian people refuse the system but nobody [could] talk. We [didn’t] have the right to speak,” Melhem said.
“After this system fell down, all of the Syrian people are speaking a lot about their experience. All of them have an experience of somebody who died, somebody who have a criminal action on them,” Melhem said.
The collapse of Assad’s government last weekend ended 14 years of conflict between Damascus — backed by Russia and Iran — and a patchwork of anti-government forces, some supported by foreign nations including Turkey and the Gulf states.
Who will lead the next government remains unclear. Hayat Tahrir al-Sham — an Islamist group which has its roots in al-Qaeda — led the surprise offensive that eventually toppled Assad.
HTS leader Abu Mohammed al-Jolani, whose real name is Ahmed al-Sharaa, has vowed to punish those accused of involvement in the torture, killings and disappearances that long characterized Assad family rule in Syria.
“We will not hesitate to hold accountable the criminals, murderers, security and army officers involved in torturing the Syrian people,” Jolani said in a statement posted to the rebels’ Military Operations Command Telegram channel.
“We will pursue war criminals and demand them from the countries to which they fled so that they may receive their just punishment,” he added.

Biden administration sets ambitious greenhouse gas emissions goal
The Biden administration only has a month left, but that’s not stopping it from taking some significant climate actions. On Wednesday, they approved California’s request to phase out the sale of new gas-powered cars. On Thursday, the administration announced an ambitious new climate goal to reduce the country’s greenhouse gas emissions by 61% to 66% compared to 2005 levels by 2035.
The countries that signed the Paris Agreement in 2016, the historic climate treaty, agreed to set goals for reducing their emissions. These Nationally Determined Contribution, or NDC, goals are updated every five years. While nonbinding, the goals provide a road map for reaching carbon neutrality globally.
“I’m proud that my Administration is carrying out the boldest climate agenda in American history,” President Joe Biden said in a video announcing the pledge. “That is why I’m proud to announce an ambitious new goal: cut greenhouse gas emissions by more than 60% by 2035.”
Biden touted his administration’s efforts to increase renewable energy sources, conserve the country’s public lands and waters, set new pollution-cutting standards and sign climate investments into law over the last four years.
The new emissions goal comes as other countries are submitting their NDCs to the United Nations for approval.
The Paris Agreement aims to limit global warming to 1.5 degrees C above pre-industrial levels, which scientists believe would significantly reduce the impacts of climate change.
In 2021, Biden re-entered the Paris Agreement after then-President Donald Trump pulled the U.S. out of the international climate accord and set the current target of 50% to 52% greenhouse gas emissions by 2030, compared to 2005 levels.
In announcing the new goal, Biden said, “Together, we will turn this existential threat into a once-in-a-generation opportunity to transform our nation for generations to come.”
During his campaign, President-elect Trump said he would pull the U.S. out of the Paris Agreement again and pledged to reduce or eliminate climate and environmental regulations.
Despite the expected change in federal posture on climate action, senior Biden administration officials told reporters Wednesday that non-federal leaders, like governors and mayors, can continue to drive progress, saying they believe the new goals are still achievable through state, local and tribal action.

Senate committee says insurance is getting more expensive because of climate change
Climate change is making it more expensive for many Americans to insure and protect their homes and property. That’s the finding of a two-year investigation by the Senate Budget Committee.
“Climate change is no longer just an environmental problem, is our conclusion here — it is an economic threat,” Sen. Sheldon Whitehouse (D-R.I.), chairman of the Senate Budget Committee, said during a hearing on Wednesday. “And it is an affordability issue that we should not ignore.”
The final hearing coincided with the release of a report from the committee detailing how extreme weather events made more severe by climate change is driving increasing both insurance policy non-renewal rates and premium costs across the country.
“The data released with this report demonstrate climate change beginning to upend insurance markets around the country,” the report reads.
Benjamin Keys, a real estate and finance professor at the University of Pennsylvania’s Wharton School, testified before the committee, saying, “Both affordability and accessibility issues have reached a crisis point in many communities around the country.”
He explained that the data shows the rate of policy non-renewals have almost doubled since 2020.
“The most striking pattern from the data is that both premiums and non-renewal rates are higher in markets with more disaster risk,” Keyes said.
“Insurers are responding to larger realized disaster losses, better data and risk models and growing reinsurance costs,” Keys explained. “Some of the largest insurance companies have exited markets, deciding that they cannot charge premiums that adequately reflect this growing risk.”
Ranking member Sen. Chuck Grassley (R-Iowa) expressed disappointment that the committee spent so much time on this issue. However, he said he agrees that “climate change is a serious issue meriting discussion.”
“I remain convinced that the budget committee should be focused on the immediate fiscal problems facing our country,” Grassley said.
“The climate crisis that is coming our way is not just about polar bears. It’s not just about green jobs. It actually is coming through your mail slot in the form of insurance cancellations, insurance non-renewals and dramatic increases in insurance costs,” Whitehouse said while closing the hearing.

DOE liquid natural gas report finds future production a risk to US climate goals
A new United States Department of Energy analysis on liquefied natural gas exports finds that continued production increases are inconsistent with U.S. climate goals, could increase energy costs and present community health concerns.
“Over the past five years, the U.S. has dramatically accelerated the pace of its LNG exports. The stocks that the department has already approved are more than sufficient to meet global demand for decades,” Energy Secretary Jennifer Granholm said Tuesday. “Further increasing exports, unconstrained, would surely generate more wealth for the LNG industry, but American consumers and communities and our climate would pay the price.”
Liquified natural gas, or LNG, is a natural gas that has been cooled into its liquid state so that it can be more easily shipped and stored, according to the DOE.
The U.S. became the largest LNG exporter in the world in 2023, according to the U.S. Energy Information Administration.
The DOE analysis, released Tuesday, found that LNG exports account for nearly half of domestic LNG production. It also found that current export volumes are expected to double by 2030, at which point the department expects the U.S. will exceed other countries’ exports by about 40%.
“With additional unfettered exports, wholesale domestic natural gas prices would increase by over 30% and the average American household will pay more than an extra $100 annually on their gas bills,” Granholm said.
The secretary added that communities “living in the shadows of LNG export projects” would be subject to even higher methane levels, nitrogen oxides and particulate matter. She said the annual direct emissions associated with exports in 2050 would represent more than 25% of our yearly greenhouse gas emissions.
Tuesday’s report has been in the works since January when the Biden Administration announced a pause on approvals for new LNG export terminals while the agency re-assessed whether such projects were in the “public interest.”
Under the authority of the National Gas Act, the DOE can make such determinations for exports to countries that are not part of a Free Trade Agreement with the U.S.
Earlier this year, President Biden said the pause “sees the climate crisis for what it is: the existential threat of our time.”
The incoming Trump Administration is expected to reverse course and expedite LNG export projects that are still awaiting approval as part of an effort to establish “energy dominance.”
The analysis released Tuesday will have a 60-day public comment period.

How climate change is transforming the winter season
Don’t let the recent blasts of cold and snow impacting much of the U.S. fool you. Meteorological winter, which started Dec. 1, is most of the country’s fastest-warming season, according to the National Oceanic and Atmospheric Administration (NOAA). And the impacts of this warming are intensifying with each passing year.
While cold and snowy conditions will continue to be a part of winter weather across the country, the global climate continues to warm at an accelerating rate. This long-term warming trend continues to fuel an overall decline in snow and extreme cold events across the U.S. and worldwide.
Our winter wonderlands are changing from white to wet as increased rainfall replaces snowfall and warmer temperatures make it difficult for snow to stay on the ground. This impacts everything from winter tourism to local ecosystems and agriculture. The multi-billion dollar winter tourism industry has already lost revenue due to the decrease in snow days, according to the Fifth National Climate Assessment.
While there is a good understanding of the general long-term trends and impacts of a warming winter season, we still have much to learn about how these changes explicitly impact a local area.
Climate Central is shedding some light on local impacts in a new report. The nonprofit climate research group compared the number of above-freezing winter days to historical averages and investigated any links to climate change.
The report estimates that in the U.S., 28 states and around 63% (39 out of 62) of the cities analyzed experienced, on average, an additional week’s worth of above-freezing winter days over the past decade. In other words, these days felt less like winter and more like the start of spring.
Specific location-based data like this could be extremely valuable to a ski resort by helping them allocate resources for an upcoming winter season or planning their long-term business strategy. While smaller-scale climate change attribution is still a relatively new area of climate science, further advancements could provide a vital resource as the world adapts to our changing climate.

More than three-quarters of the planet’s land is now permanently drier due to climate change
Humans are dependent on the land for our very survival. If we can’t farm, we don’t eat. However, much of that precious soil is in danger due to human-amplified climate change, according to a new report.
In its new report, the U.N. Convention to Combat Desertification (UNCCD) found that 77.6% of the Earth’s land has become permanently drier over the last three decades leading up to 2020. During the same period, drylands expanded by more than 1.6 million square miles and now cover more than 40% of the planet (excluding Antarctica).
Drylands are regions characterized by low rainfall and moisture, resulting in scarce water and arid land. Drier land can result in insufficient food production, increased wildfire activity, water scarcity and land degradation, according to the report.
“Unlike droughts—temporary periods of low rainfall—aridity represents a permanent, unrelenting transformation,” UNCCD Executive Secretary Ibrahim Thiaw said in a press statement. “Droughts end. When an area’s climate becomes drier, however, the ability to return to previous conditions is lost. The drier climates now affecting vast lands across the globe will not return to how they were and this change is redefining life on Earth.”
The report says human-amplified climate change is the primary reason for this transformation. The UNCCD finds that greenhouse gas emissions from electricity generation, transportation, industry and land use changes are warming the planet and affecting rainfall, evaporation and plant life. They say those changes create the ideal conditions for increased dryness.
And it’s not just dry areas getting drier. The researchers found that more than 7% of global lands were transformed from non-drylands to drylands or from less arid areas to more arid. They warn that another 3% of the world’s humid areas could become drylands by the end of the century if we don’t reduce greenhouse gas emissions.
“Without concerted efforts, billions face a future marked by hunger, displacement, and economic decline. Yet, by embracing innovative solutions and fostering global solidarity, humanity can rise to meet this challenge. The question is not whether we have the tools to respond—it is whether we have the will to act,” Nichole Barger, chair of the UNCCD’s science-policy interface, said in a statement.
The report makes several recommendations, including better monitoring, improved land use policies and investing in new water efficiency technologies. But they make it clear that the world must curb global warming if they are to stop the future damage and the threats that come from it.

Report finds that geothermal energy could meet 15% of global energy demand through 2050
The Earth produces a lot of heat. Scientists believe our planet’s inner core is nearly as hot as the sun. Radioactive particles in rocks slowly decay, constantly replenishing the heat. Geothermal energy harnesses that heat to create energy and warm homes and buildings.
However, geothermal energy isn’t widely used despite being clean and renewable. It’s expensive and often location-specific, usually near tectonic plate boundaries.
But according to a new report from the International Energy Agency (IEA), geothermal power could become a significant source of electricity for the world. The intergovernmental organization found that “geothermal energy could meet 15% of global electricity demand growth between now and 2050 if project costs continue to decline.”
That would be enough power to meet the current demand of the United States and India combined. Unlike wind and solar, the IEA says geothermal can provide 24/7 energy generation. It also has the added benefit of heat production and storage.
“New technologies are opening new horizons for geothermal energy across the globe, offering the possibility of meeting a significant portion of the world’s rapidly growing demand for electricity securely and cleanly,” IEA Executive Director Fatih Birol said in a press statement.
The IEA says with more financial investment, the cost of geothermal energy could fall by 80%. And at a time when finding workers with green energy skills can be challenging, the report states “up to 80% of the investment required in geothermal involves capacity and skills that are transferrable from existing oil and gas operations.”
“Geothermal is a major opportunity to draw on the technology and expertise of the oil and gas industry. Our analysis shows that the growth of geothermal could generate investment worth $1 trillion by 2035,” Birol added.
November was the 2nd warmest on record
With less than three weeks to go before 2025, global temperatures in November have made it all but certain that 2024 will be the warmest year ever recorded.
According to NOAA’s monthly climate assessment, last month was the second warmest November globally, with temperatures 2.41 degrees Fahrenheit above the 20th-century average. Temperatures were above average across much of the world, with Asia experiencing its warmest November ever recorded. Oceania and South America were second-warmest.
Year-to-date, the world is experiencing its warmest period on record. That means there’s a more than 99% chance that 2024 will break the yearly temperature record currently held by 2023, according to the National Centers for Environmental Information.
According to NOAA, global tropical cyclone activity matched the long-term record with 12 named storms this year. The Atlantic saw three hurricanes in November, including Rafael, which peaked as a Category 3 storm.
Global sea ice area was the second smallest in 46 years and more than one million square miles less than the 1991-2020 average.

Wildfire smoke: A significant contributor to air pollution in some US communities
In recent years, wildfire smoke has emerged as a significant cause of diminished air quality across many cities in the United States, according to a new recent study presented at the American Geophysical Union annual meeting in Washington, D.C.
The findings, which have not yet been peer-reviewed, suggest that wildfire smoke can contribute to as much as 50% of annual air pollution in certain parts of the U.S. Regions in Oregon, Nevada, California, Washington, North Dakota and Minnesota were identified as some of the most affected by this smoke-related air pollution.
The researchers say the impact of wildfire smoke doesn’t just stop in remote areas; it’s also impacting major urban centers. Some of the country’s largest cities, including New York, Dallas, Chicago, Atlanta and Washington, D.C., reported significant smoke exposure in 2023. Los Angeles, Phoenix and Riverside experienced their highest smoke levels in 2020. The researchers say this year-to-year variation between locations underscores the unpredictable nature of wildfire seasons and their far-reaching consequences on air quality.
The researchers analyzed data collected from more than 800 particle monitors in over 350 areas, representing nearly 90% of the U.S. population. The team combined data from the NOAA Hazard Mapping System Fire and Smoke Product with surface PM2.5 readings to explore how these smoky days affect overall pollution levels. PM2.5 is a type of particulate matter pollution smaller than human hair that can cause a number of health problems, such as asthma and heart disease.
The results from the study raise important questions about public health and environmental policy, especially as climate change intensifies wildfire seasons. According to a study from researchers at the University of Tasmania, extreme wildfire events have more than doubled in frequency and magnitude globally over the past two decades. And the Environmental Protection Agency has found that the U.S. wildfire season has grown longer and shifted earlier in recent decades due to warmer springs, longer summer dry seasons and drier vegetation.

The rapidly warming Arctic tundra is now contributing to climate change
For thousands of years, the vast Arctic tundra has acted as a critical carbon sink. That means it absorbed more carbon dioxide than it produced. As a result, it has been removing a heat-trapping greenhouse gas from the atmosphere. However, rapidly warming conditions and increasing wildfire activity have now turned the region into a source of carbon dioxide emissions, according to a new report released by the National Oceanic and Atmospheric Administration (NOAA).
The Arctic region is warming much faster than the global average, and rapidly warming temperatures are fueling the troubling shift in several ways.
First, increasing temperatures are thawing the permafrost, releasing carbon that’s been stored in the soil into the atmosphere. Second, warmer conditions promote vegetation growth, contributing to more frequent wildfires in the region and additional carbon dioxide emissions.
The Arctic’s warmest years on record have all occurred within the last nine years. The persistent warming trend has contributed to declining snow cover and a shortening snow season. According to the report, last winter brought the shortest snow season in 26 years for portions of Arctic Canada, and overall, Arctic snow melt is occurring one to two weeks earlier than historical averages.
Less snow promotes further warming and increases the wildfire threat in the region. And these compounding factors create an unsettling cycle that feeds on itself, boosting global warming while making it increasingly difficult to reduce carbon dioxide emissions.
Rick Spinrad, NOAA’s administrator, said the addition of the Arctic tundra as a source of carbon dioxide emissions “will worsen climate change impacts.”
Local ecosystems are already having to adapt. According to the report, food sources for ice seal populations are shifting due to water temperature changes and warmer and wetter weather is devastating inland caribou herds.
If this trend continues, cascading impacts could reach far beyond the Arctic region. “What happens in the Arctic has wide-reaching implications for the entirety of North America and Eurasia,” Dr. Brenda Ekwurzel, a climate scientist at the Union of Concerned Scientists, said in a press statement.

The US just experienced its warmest autumn on record
Another season, another climate milestone. According to a new report from the National Oceanic and Atmospheric Administration (NOAA), persistent above-average to record-warm conditions across much of the United States made meteorological autumn, which lasts from September to November, the warmest ever recorded.
The record-warm fall season makes it more likely that 2024 will end up as one of the nation’s warmest, if not the warmest, years on record. As of November 2024, the contiguous U.S. year-to-date temperature was 3.3 degrees Fahrenheit above average.
Despite December’s chilly start for much of the country, with widespread below-average temperatures in many regions, NOAA’s Climate Prediction Center says that the cold will ease during the second half of the month with above-average temperatures favored from the West to the Northeast.
The stretch of abnormally warm temperatures was accompanied by extremely dry weather across much of the country, fueling dangerous wildfire conditions in regions like the Northeast. A very dry start to the season brought drought conditions to more than half of the lower 48 states by late October.
Fortunately, several significant rainfall events in November brought notable drought relief to large swaths of the country, reducing overall drought coverage by nearly 10.5% and suppressing the wildfire danger.

Nearly one-third of the planet’s species risk extinction because of climate change
Nearly one-third of the world’s species could be at risk for extinction because of climate change if the world does nothing to reduce global warming, according to a new analysis from Science.
University of Connecticut researcher and biologist Mark Urban found that while some species are adapting to climate change, 160,000 species are already at risk. Many are now facing declining populations because of changes in our climate.
According to the study, with current global temperatures at 1.3 degrees Celsius above industrial levels, 1.6% of species are projected to become extinct. As the temperatures warm even more, Urban found the extinction rate would also increase, with the most severe scenario included (5.4 degrees Celsius of warming) putting the extinction risk at 29.7%.
“The increased certainty of predicted climate change extinctions compels action,” Urban wrote. “Extinction represents just the final endpoint of a species’ existence; even when extinction is avoided, declining abundances and shrinking ranges can strongly affect many other species, including humans.”
Urban defines the risk of extinction as the probability that any one species will go extinct without mitigation efforts. Urban found that extinction rates could increase dramatically if global temperatures rise over 1.5 degrees Celsius compared to industrial levels.
1.5 degrees Celsius is the warming limit set by the world’s nations under the Paris Agreement after the United Nations Intergovernmental Panel on Climate Change found that crossing that benchmark would lead to more severe climate change impacts.
Risks varied across geographic areas in the study, with Australia/New Zealand and South America facing the highest risks (15.7% and 12.8%, respectively) and Asia facing lower risks (5.5%).

Antarctic sea ice hits new low during Earth’s 2nd warmest November on record
Imagine you have a swimming pool with ice cubes filling it. Now, measure the total area of the pool that has ice on the surface, even if the ice cubes don’t cover it completely. Because ice often spreads out unevenly, leaving water between the chunks, scientists count areas where at least 15% of the surface is covered. So, because your pool is loaded with ice cubes, it would be considered ice covered. In the real world, scientists call it sea ice extent.
While you can add ice to your pool, you can’t to the ocean. And according to a new report by Copernicus, the European Union’s Climate Change Service, the sea ice extent in the Antarctic has dipped to its lowest value on record for the month of November. It is 10% below average. This occurred during a stretch of near-record global land and sea surface temperatures.
Last month ranked as the second warmest November on record globally, with an average temperature of 14.10 degrees Celsius, or 57.38 degrees Fahrenheit.
Copernicus noted the new data not only makes it virtually certain that 2024 will surpass 2023 as Earth’s warmest year on record, but it will likely be the first year to be 1.5 degrees Celsius warmer (2.7 degrees Fahrenheit) than the pre-industrial average of 1850-1900.
The Paris Agreement aims to limit global warming to 1.5 degrees Celsius to prevent the worst outcomes of climate change.
As of November 2024, the average global year-to-date temperature was 0.14 degrees Celsius (or 0.25 degrees Fahrenheit) higher than it was in 2023, which is the warmest year ever recorded.
